# Editable

`public interface Editable`
`implements CharSequence, GetChars, Spannable, Appendable`

android.text.Editable

Known indirect subclasses SpannableStringBuilder
SpannableStringBuilder | This is the class for text whose content and markup can both be changed.

This is the interface for text whose content and markup can be changed (as opposed to immutable text like Strings). If you make a `DynamicLayout` of an Editable, the layout will be reflowed as the text is changed.

## Summary

### Nested classes
`class` | `Editable.Factory` Factory used by TextView to create new `Editable`.

### Inherited constants
From interface `android.text.Spanned`
`int` | `SPAN_COMPOSING` This flag is set on spans that are being used to apply temporary styling information on the composing text of an input method, so that they can be found and removed when the composing text is being replaced.
`int` | `SPAN_EXCLUSIVE_EXCLUSIVE` Spans of type SPAN_EXCLUSIVE_EXCLUSIVE do not expand to include text inserted at either their starting or ending point.
`int` | `SPAN_EXCLUSIVE_INCLUSIVE` Non-0-length spans of type SPAN_EXCLUSIVE_INCLUSIVE expand to include text inserted at their ending point but not at their starting point.
`int` | `SPAN_INCLUSIVE_EXCLUSIVE` Non-0-length spans of type SPAN_INCLUSIVE_EXCLUSIVE expand to include text inserted at their starting point but not at their ending point.
`int` | `SPAN_INCLUSIVE_INCLUSIVE` Spans of type SPAN_INCLUSIVE_INCLUSIVE expand to include text inserted at either their starting or ending point.
`int` | `SPAN_INTERMEDIATE` This flag will be set for intermediate span changes, meaning there is guaranteed to be another change following it.
`int` | `SPAN_MARK_MARK` 0-length spans with type SPAN_MARK_MARK behave like text marks: they remain at their original offset when text is inserted at that offset.
`int` | `SPAN_MARK_POINT` SPAN_MARK_POINT is a synonym for `SPAN_INCLUSIVE_INCLUSIVE`.
`int` | `SPAN_PARAGRAPH` SPAN_PARAGRAPH behaves like SPAN_INCLUSIVE_EXCLUSIVE (SPAN_MARK_MARK), except that if either end of the span is at the end of the buffer, that end behaves like _POINT instead (so SPAN_INCLUSIVE_INCLUSIVE if it starts in the middle and ends at the end, or SPAN_EXCLUSIVE_INCLUSIVE if it both starts and ends at the end).
`int` | `SPAN_POINT_MARK` SPAN_POINT_MARK is a synonym for `SPAN_EXCLUSIVE_EXCLUSIVE`.
`int` | `SPAN_POINT_MARK_MASK` Bitmask of bits that are relevent for controlling point/mark behavior of spans.
`int` | `SPAN_POINT_POINT` 0-length spans with type SPAN_POINT_POINT behave like cursors: they are pushed forward by the length of the insertion when text is inserted at their offset.
`int` | `SPAN_PRIORITY` The bits specified by the SPAN_PRIORITY bitmap determine the order of change notifications -- higher numbers go first.
`int` | `SPAN_PRIORITY_SHIFT` The bits numbered just above SPAN_PRIORITY_SHIFT determine the order of change notifications -- higher numbers go first.
`int` | `SPAN_USER` The bits specified by the SPAN_USER bitfield are available for callers to use to store scalar data associated with their span object.
`int` | `SPAN_USER_SHIFT` The bits numbered SPAN_USER_SHIFT and above are available for callers to use to store scalar data associated with their span object.

### Inherited methods
From interface `java.lang.CharSequence`
`abstract char` | `charAt(int index)` Returns the `char` value at the specified index.

`abstract <T> T[]` | `getSpans(int start, int end, Class<T> type)` Return an array of the markup objects attached to the specified slice of this CharSequence and whose type is the specified type or a subclass of it.
`abstract int` | `nextSpanTransition(int start, int limit, Class type)` Return the first offset greater than `start` where a markup object of class `type` begins or ends, or `limit` if there are no starts or ends greater than `start` but less than `limit`.

## Public methods

### append

    public abstract Editable append (char text)

Convenience for append(String.valueOf(text)).

Parameters
`text` | `char`: The character to append

Returns
`Editable` | A reference to this `Appendable`

See also:

- `replace(int, int, CharSequence, int, int)`

### append

    public abstract Editable append (CharSequence text,
                    int start,
                    int end)

Convenience for replace(length(), length(), text, start, end)

Parameters
`text` | `CharSequence`: The character sequence from which a subsequence will be appended. If `csq` is `null`, then characters will be appended as if `csq` contained the four characters `"null"`.
`start` | `int`: The index of the first character in the subsequence
`end` | `int`: The index of the character following the last character in the subsequence

Returns
`Editable` | A reference to this `Appendable`

See also:

- `replace(int, int, CharSequence, int, int)`

### append

    public abstract Editable append (CharSequence text)

Convenience for replace(length(), length(), text, 0, text.length())

Parameters
`text` | `CharSequence`: The character sequence to append. If `csq` is `null`, then the four characters `"null"` are appended to this Appendable.

Returns
`Editable` | A reference to this `Appendable`

See also:

- `replace(int, int, CharSequence, int, int)`

### clear

    public abstract void clear ()

Convenience for replace(0, length(), "", 0, 0). Note that this clears the text, not the spans; use `clearSpans()` if you need that.

See also:

- `replace(int, int, CharSequence, int, int)`

### clearSpans

    public abstract void clearSpans ()

Removes all spans from the Editable, as if by calling `Spannable.removeSpan(Object)` on each of them.

### delete

    public abstract Editable delete (int st,
                    int en)

Convenience for replace(st, en, "", 0, 0)

Parameters
`st` | `int`
`en` | `int`

Returns
`Editable` |

See also:

- `replace(int, int, CharSequence, int, int)`

### getFilters

    public abstract InputFilter[] getFilters ()

Returns the array of input filters that are currently applied to changes to this Editable.

Returns
`InputFilter[]` |

### insert

    public abstract Editable insert (int where,
                    CharSequence text)

Convenience for replace(where, where, text, 0, text.length());

Parameters
`where` | `int`
`text` | `CharSequence`

Returns
`Editable` |

See also:

- `replace(int, int, CharSequence, int, int)`

### insert

    public abstract Editable insert (int where,
                    CharSequence text,
                    int start,
                    int end)

Convenience for replace(where, where, text, start, end)

Parameters
`where` | `int`
`text` | `CharSequence`
`start` | `int`
`end` | `int`

Returns
`Editable` |

See also:

- `replace(int, int, CharSequence, int, int)`

### replace

    public abstract Editable replace (int st,
                    int en,
                    CharSequence source,
                    int start,
                    int end)

Replaces the specified range (`st…en`) of text in this Editable with a copy of the slice `start…end` from `source`. The destination slice may be empty, in which case the operation is an insertion, or the source slice may be empty, in which case the operation is a deletion.

Before the change is committed, each filter that was set with `setFilters(InputFilter[])` is given the opportunity to modify the `source` text.

If `source` is Spanned, the spans from it are preserved into the Editable. Existing spans within the Editable that entirely cover the replaced range are retained, but any that were strictly within the range that was replaced are removed. If the `source` contains a span with `Spanned#SPAN_PARAGRAPH` flag, and it does not satisfy the paragraph boundary constraint, it is not retained. As a special case, the cursor position is preserved even when the entire range where it is located is replaced.

Parameters
`st` | `int`
`en` | `int`
`source` | `CharSequence`
`start` | `int`
`end` | `int`

Returns
`Editable` | a reference to this object.

See also:

- `Spanned.SPAN_PARAGRAPH`

### replace

    public abstract Editable replace (int st,
                    int en,
                    CharSequence text)

Convenience for replace(st, en, text, 0, text.length())

Parameters
`st` | `int`
`en` | `int`
`text` | `CharSequence`

Returns
`Editable` |

See also:

- `replace(int, int, CharSequence, int, int)`

### setFilters

    public abstract void setFilters (InputFilter[] filters)

Sets the series of filters that will be called in succession whenever the text of this Editable is changed, each of which has the opportunity to limit or transform the text that is being inserted.

Parameters
`filters` | `InputFilter`
